RT Journal Article T1 Power-series solution of compartmental epidemiological models A1 Srivastava, H. M. A1 Area Carracedo, Iván Carlos A1 Nieto, J. J. K1 12 Matemáticas K1 3202 Epidemiología K1 1206 Análisis Numérico AB In this work, power-series solutions of compartmental epidemiological models are used to provide alternate methods to solve the corresponding systems of nonlinear differential equations. A simple and classical SIR compartmental model is considered to reveal clearly the idea of our approach. Moreover, a SAIRP compartmental model is also analyzed by using the same methodology, previously applied to the COVID-19 pandemic. Numerical experiments are performed to show the accuracy of this approach PB Mathematical Biosciences and Engineering SN 15510018 YR 2021 FD 2021-04-12 LK http://hdl.handle.net/11093/3013 UL http://hdl.handle.net/11093/3013 LA eng NO Mathematical Biosciences and Engineering, 18(4): 3274-3290 (2021) NO Agencia Estatal de Investigación de España | Ref.
